What pLDDT means and how to read it

Function

Transcription regulator that acts both as a histone methyltransferase or chromatin adapter, depending on the context (PubMed:12816872). In the cytoplasm, acts as a histone methyltransferase, which catalyzes monomethylation of 'Lys-9' of free histone H3 (H3K9me1) during translation (By similarity). Monomethylated histone H3 is then transported to the nucleus and incorporated into nucleosomes where SUV39H methyltransferases (SUV39H1 and SUV39H2) use it as a substrate to catalyze histone H3 'Lys-9' trimethylation (H3K9me3) (By similarity). Probably one of the primary histone methyltransferases along with MECOM/PRDM3 that direct cytoplasmic H3K9me1 methylation (By similarity). In the nucleus,…

Subunit structure

Interacts with CEBPA, CEBPB and CEBPD; the interaction is direct (By similarity). Interacts with PPARG; controls brown adipocytes (By similarity). Interacts with CTBP1 and CTBP2; represses the expression of white adipose tissue-specific genes (By similarity). Interacts (via N-terminus) with RBBP4 (PubMed:30462309). Interacts with PPARGC1A and PPARGC1B; interaction with PPARGC1A or PPARGC1B…
